However, this solution also has some drawbacks. The method comprises the following steps: the reinforcement cage of the SPCS cavity post-cast precast column is pre-buried in the concrete shell, the concrete shell and the reinforcement cage pre-buried in the concrete shell are required to be transported integrally during transportation, so that the concrete shell is easy to break down, the weight of the concrete cage is relatively large, larger hoisting equipment is required during hoisting, and the field hoisting difficulty is increased.
